Abstract:Nodal regments of tropical fruit Averrhoa carambola (Oxalidaceae) were used as explants to investigate optimum conditions for rapid propagation. Among cytokinins (1.0 mg L-1), zeatin (1.0 mg L-1) was best for culture, and kinetin (1.0 mg L-1) the worst. MS medium supplemented with 0.5 mg L-1 BA, 0.2 mg L-1 NAA and 0.2 mg L-1 GA was optimal for the plantlet growth, the proliferation coefficient being as high as 3.7, and the rate of abnormal plantlets was only 23.3%. As for rooting, half-strengh MS medium containing 0.2 mg L-1 IBA，0.1 mg L-1 and 2％-3％ sucrose was the best．The rooting rate was 87.1％ ．
